There are some photos of camphor trees.

Cinnamomum camphora has different varieties, which can be divided into Cinnamomum camphora and Cinnamomum camphora.

Cinnamomum macrophyllum (Cinnamomum of Lauraceae) is 5-8( 16) meters high and DBH is 40 cm. The bark is grayish brown. Panicles are born in the axils of annual branches, branched three times, and the last branch is usually a cyme of 3 flowers. Fruit elliptic, receptacle shallowly cup-shaped, margin shallowly dentate, and tooth apex truncate. The flowering period is from June to August, and the fruiting period is from August to June.

Cinnamomum camphora is a perennial plant with lateral rhizomes. The culms are erect, smooth and hairless, 90- 150 cm in height and 1-4 mm in diameter, usually branched. Leaf sheaths shorter than internodes, smooth and glabrous; Ligule oblong, 6- 10 mm long, blunt or brittle at the top; Leaf blade linear, flat, long 15-30 cm, wide 3-8 mm, slightly rough on both sides.

Extended data:

Cinnamomum camphora likes light, seedlings and young trees are shade-tolerant and like warm and humid climate. They are not cold-tolerant, they are afraid of cold. The lowest temperature in winter can't be lower than 0 degrees, which will cause frostbite. If it is lower than 5-8 degrees below zero, it will cause frostbite and death.

Cinnamomum camphora grows well in deep, fertile and moist acidic or neutral yellow soil and red soil, and is not tolerant to drought, barren and saline-alkali, with strong germination and pruning resistance. Strong resistance to sulfur dioxide, ozone and smoke pollution, and can absorb a variety of toxic gases.

Cinnamomum camphora is mainly distributed in the south of the Yangtze River valley in China, with Jiangxi, Zhejiang, Taiwan Province, Guangdong, Fujian and other southern regions being the most abundant. Most of them are born in sunny slopes, hills and valleys of low mountains, and their vertical distribution is mostly below 500~600m above sea level. There are natural camphor trees in the mountainous areas in the north-central part of Taiwan Province Province at an altitude of 1800 meters. It grows most vigorously below 1500m and is an important tree species in subtropical evergreen broad-leaved forest in China.
